British manned spacecraft. Study 2004. X-Prize suborbital ballistic spacecraft concept of Flight Exploration of London, England.
The Green Arrow was a design of Flight Exploration of London, England, designed by a team led by Dr Graham Dorrington. The vehicle was based on the hydrogen peroxide rocket engine technology successfully developed in the UK during the 1950's and 1960's, then abandoned by the government. Green Arrow used conventional rocket powered vertical takeoff and parachute landing. The prototype vehicle was to have an all up mass of 20,000 kg at takeoff and a lightweight composite structure permitting a mass ratio of 0.3.
Gross mass: 20,000 kg (44,000 lb).

Unfuelled mass: 6,000 kg (13,200 lb).
X-Prize The X-Prize competition was an attempt to promote commercial civilian spaceflight in a manner similar to the prizes handed out in the early days of aviation. Ten million dollars was to go to the first team to fly a vehicle capable of launching three people into space (defined as an altitude of 100 km in a suborbital trajectory), twice in a two-week period. The vehicle had to be 90% reusable by dry mass. For purposes of the two flights, the competition accepted flight by one person and ballast equivalent to two others at 90 kg per passenger. More...
